STAGKIITG- STEM FOR COIN-COUNTING EEACHINES.

I Application filed March 20 1925. Serial No. 17,071

- tormedinto a roll containing a definite numher Oil coins, and my inventionparticularly relates to the stacking stems in which these rolls of coins are stacked.

In machines of this character a delinite number of coins are usually delivered to a spout to which is attached a stacking stem of suitable diameter as required by the particular denomination of, the coins to be counted, Into this tube is inserted the coin wrapper, to receive the coins, which is withdrawn when the proper number of coins have been delivered. It sometimes happens that the coins as they drop into the tube become jammed and fail to tall into the package. It also otten. happens that the coins in moving in avertical plane with reference to the stem strike the sides of the wrapper and stick. Then coins dropping one by one into a package have not enough weight to overcome a frictional engagement with the wrapper.

It is my object to provide means for holding back a predetermined number of coins and then projecting them sideways into the w apper where the weight of the coins and their velocity in the stem will cause them to fall rapiiflly into the wrapper.

liurther it is my object to construct the stacking stems so that the operator may see while the coins are being delivered both that the coins are delivered properly from the machine in the correct number, and if any jamming ot' the coins has happened that correction may be made before the coins are de posited in the wrapper.

In the drawing: Figure 1 is a perspective View oi the coin tube.

Figure 2 is a longitudinal section oithe tube along the lines 22 of Figure 1? Figure 3 is a section along the lines 3-3 of Figure 1.

There is shown generally indicated at 1, the main body portion of the device. In the particular stem shown a groove 2 is disposed in a flanged portion 8 in. the top part of the stem. A strap or clamp fits in this groove and thereby supports it in the discharge compartinent oi the coin fillingmachine with the stem extending preferably down and outwardly from the machine in a diagonal. direction. The method and the position of support is, however, immaterial inasmuch as it terms no partot this invention. The inner portion 4- of the stem tapers,inwardly from the base 5, and the tubular wrapner S is held at the top of this tapered portidn. The upper portion oi the stem tapers ,on its inner side more gradually than the base as shown at 6 At the bottom of the upper tapered portion the inner walls 7 of the tube eiitend straight down to the tapered portion of the walls at the base. Partway up in the cylindrieal walls removed from the tapered portion of the base suiliciently to permit a drop of the coins into the wrapper is a slot m which a shutter t) is retained; A boss 10 extends out from the outer walls of the stem and a pin 11 retained in the boss is the pivot for the shutter 9. A spring 12 encircling the pin and attached at its upper end is hooked over the shutter to provide a tension to keep the shutter in position in the stem blocking the cylindrical aperture through it. The shutter extent s through the slot opposite the boss and a bent over end 13 is adapted for a finger grip to open and close the shutter. Disposed in position in the walls of the stem with its center adjacent the base of the upper tapered portion is an aperture 1st of a size small enough to not permit a coin to fall outand through which an operator may clearly see thecoins in the cylinder in case there is a stoppage in the upper tapered portion. In the walls of the stem adjacent the shutter another aperture 1.5 provides a peep hole through which the operator can see the coins on the shutter and it desired the coins in the top portion of the wrapper.

As noted these holes are preferably round, as shown, and of smaller size than the coin e which is to be packed in it. Slots have been found to be impractical. as the sides of the coins frequently catch in them and so block up the tube, or a coin might be discharged through a slot sutliciently long to give proper inspection. The sight openings thirther pro vide an opening through which any pointed instrument may be. inserted to clear blocked coins from the tube.

It will be observed that as the stacking stem is preferably held diagonally from the machine and as the shutter moves from one side of the tube the coinswill be tilted and fall diagonally into the wrapper. This tilting of the tube the shutter releasing one side of the bottom coin first, and "the distance vide peep holes located in several positions in the stem for the insertion of a pointed object to clear the passage.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A stacking stein for coins comprising a tubular member having a hollow cylindrical portion of suflicient size as to receive a stack of coins, said cylindrical portion being of smaller size than will accommodate a wrapper for the. coins; said cylindrical portion having a supporting shutter intermediate the ends thereof, and said cylindrical portion having an opening of sufficient sizeas to admit an instrumentto dislodgecoins in the wall there- 01 adjacent the shutter.. 2. A stacking stem for coins comprising a tubular member having a hollow cylindrical portion of sufiicient size as to receive'a stack of coins, said cylindrical portion being of smaller size than will accommodate a wrapper for the coins, said cylindrical portion having a supporting shutter intermediate the ends thereof and said cylindrical portion having an opening of sufiicient size as to admit an instrument to dislodge coins in the wall thereof at the receiving end thereof.

3. A stacking stem for coins comprising a tubular member having a hollow cylindrical portion of sufiicient size as to receive a stack 051? coins, said cylindrical portion being, of

smaller size than will accommodate a wrapper for the coins, and said tubular member having a tapered portion 'ad acent an end of the into receiving position.
